did you notice any improvement in flight with the seagull 24iv, regarding the Falcohobby22iv?

The Falcohobby seems more maniable on the videos, in spite of its "usual" wings.

The power system( motor, ESC, battery) is the same in FalcoHobby22iV, NightFury24iV, Seagull24iV.
Therefore I can compare a difference of performance of these ornithopters.
As for the flight performance of acrobatic feats, FalcoHobby22iV is the best.
A thrust of FalcoHobby22iV is the strongest, too.
As for Seagull24iV, consumption of a battery is early, and there are a most few thrusts.
The wings of Seagull24iV will be suitable for gliding.
The wings of FalcoHobby22iV is suitable for acrobatic flight.

SeaGull 24iV Good Flight and Gliding

I fly Seagull24iV without knowing that a rubber band of the left wing burst.
A rubber band power does not work on the left wing.
So, thrust is not enough.
Compare movement of the left wing ( without rubber belt ) with the right wing (with rubber belt).

Very nice flapping gull indeed with or w/o rubber band on the left wing
thanks for sharing
may I know what is the RTF weight of the bird?
best regards

New flight

Flaptter19-8 Flight with New wing
Flaptter 19-7 of LAPUTA (Hayao Miyazaki 's animation)
With new wings
I decreased the flapping amplitude of rear wings.
I changed flapping cycle of wings.
A flap cycle of front wings is delayed by 90 degrees in a flap cycle of rear wings.
Very Good Flight.

Tetrapteron12-1 of Avatar :Good Flight & Gliding
Tetrapteron is a flight creature appearing in Avatar which have two pairs of wings, twin tail, Large beak and gullet with glassy teeth.
This creature which James Cameron created has a suitable design for flight.
Hind legs work well as inverted V-shaped V-tail.

DragonFly21-11 with New Flight control system

This is a new flight control system.
Wing flapping amplitude change system.
Flight is controlled by changing the amplitude of flapping wings and spoiler-like change of both-side wings.
Changing of wing amplitude resembles the flight control system of a natural dragonfly.
An action test is good.
A flight of a short distance in the room is good.
A flight test at outdoor is not yet done.

Very good indeed!
The way some insects turn seems to be due to an independant muscular control of that point were the flapping wing is attached, thus changing the direction of air flow. This system is quite close to the latter.

Dragonfly21-11 with Wing flapping amplitude change system: Test Flight 1
This is a new flight control system.
Wing flapping amplitude change system.
Flight is controlled by changing the amplitude of flapping wings and spoiler-like change of both-side wings.
Changing of wing amplitude resembles the flight control system of a natural dragonfly.
A test flight 1 in strong wind(6-7meter/second).
Flight control by changing of Flapping amplitude is very effective.
